Submerged plant seedling cultivation system

Abstract

The invention discloses a submerged plant seedling cultivation system. The system comprises a greenhouse and a seedling breeding system arranged in the greenhouse, wherein the seedling breeding systemcomprises a load bearing frame and multiple layers of planters arranged on the load bearing frame, seedling substrates are arranged at the bottoms of the planters, a water supply pipe is connected with a water supply pump, a light control device is arranged above the planters, a plurality of water supply branch pipes are sequentially distributed at the side parts of the planters, each water supply branch pipe is communicated with the water supply pipe, a drainage pipe is communicated with the end parts of the planters, and a temperature control device is arranged in the greenhouse. The systemalso comprises a seedling hardening system and a water treatment system outside the greenhouse. Cyclic utilization of water resources and nutrients in the water resources is realized, the system is saving and environmentally friendly, and the seedling cultivation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of ecological environment engineering, and in particular relates to a submerged plant seedling cultivation system. Background technique [0002] Eutrophication of lakes and cyanobacteria blooms have become one of the main problems facing my country's water environment. The main ways to treat eutrophic water bodies are: reduction and control of exogenous pollution—reduction and control of internal pollution—restoration and reconstruction of water ecosystem. The restoration and reconstruction of aquatic ecosystems centered on the restoration of submerged plants is considered to be the most effective means to control water eutrophication and cyanobacterial blooms after pollution sources are controlled. With the widespread application of this technology in lakes and urban water bodies in my country, the demand for submerged plant seedlings has also increased significantly. [0003] At present, the seedlings us...

AI Technical Summary

Problems solved by technology

[0003] At present, the seedlings used in the submerged plant restoration project mainly come from the following methods: one is fishing from natural water bodies, but under the condition that the current water body ecosystem is generally damaged, seedling resources are often lacking, and This method also destroys the ecological environment of the provenance; the second is to establish seedling ponds, under natural environmental conditions, by planting submerged plant propagules in the seedling ponds to concentrate on obtaining a large number of seedlings, this The method can partially solve the problem of seedling supply, but the seedling pond occupies a large area, and the acquisition of seedlings is often affected by the season; the third is plant tissue culture, which can produce a large number of seedlings from several plants in a short time , and not affected by seasons, but the produced seedlings are relatively thin, difficult to harden, and the survival rate of transplanting is low
